Does not work for me. Doesn't look very "button-ish" to me either, but that's subjective.
On the bright side, the number pad positioning is better than ever!
It seems to come up in within the screen boundary much more often.
Maybe always if the puzzle fit entirely on-screen.
Larger puzzles are tougher of course, especially since one typically zooms in and out, and I'm not sure what that would do to the browser, or if the browser code would even be able to tell. But even in these cases it seems better behaved. Can't put my finger on it (pun, but had to work too hard for it, so no points awarded).
